Overall codebase audit

A documentation-only branch collecting the cross-cutting audits and planning docs for Sapling. No code changes — every finding is cited to file:line and verified against the actual code. Three documents:

1. Frontend UI audit — docs/frontend-ui-audit.md

Five-dimension technical audit of frontend/ (accessibility, performance, theming, responsive, anti-patterns), scored against WCAG 2.1 AA and the design contract in .impeccable.md.

Health score: 10/20 (Acceptable — significant work needed).

DimensionA11yPerformanceThemingResponsiveAnti-Patterns
Score2/43/42/42/41/4

Core finding: the signed-in app shell is largely on-brand, but the pre-auth landing + onboarding break four of the project's own hard bans (glassmorphism, gradient text, hero-metric cards, an orphaned dark-mode stylesheet). Much of the remediation is deletion, not redesign.

Tracked by epic #113 with 11 grouped issues:

2. Backend & contract bug audit — docs/backend-contract-bug-audit.md

Functional-correctness audit of backend/ and the frontend↔backend API contract. Eight domain auditors fanned out in parallel; every candidate was handed to a separate verifier instructed to refute it. 40 candidates → 34 confirmed → 31 distinct bugs.

SeverityCountTheme
Critical2Cross-user IDOR + encrypted chat rendered as ciphertext
High6Encryption-boundary breaks, cross-user LLM context leak, agent-migration regressions, dead admin endpoint
Medium9Concurrency/idempotency, pipeline double-fire, empty-OCR persistence, missing usage limits
Low14Response-boundary ciphertext, off-by-ones, dedup/escaping, contract drift

Most urgent:calendar.export_to_google (backend/routes/calendar.py:378-407) is a cross-user IDOR that exfiltrates other users' decrypted private assignment notes — patch first, then the two encryption boundaries, then the knowledge-graph correctness cluster.

Tracked by epic #136, findings grouped into issues #123#135 (overlapping pre-existing issues #85, #72, #74, #61 were cross-linked and de-duplicated rather than re-filed).

3. Site logging & usage tracking epic — docs/observability-logging-tracking.md

Forward-looking plan (not an audit) for owned logging + usage analytics: Supabase events + llm_usage tables, a fire-and-forget write path, Logfire activation for ops/LLM tracing, an admin analytics API, and a dashboard. Broken into issues #115#122 with ownership (Luke / Andres / Jack / Jose), a dependency graph, and build order.

Scope

Documentation only — a shared docs branch consolidating audit + planning artifacts. Reviewers can treat each doc independently; the bug audits drive remediation issues, and the observability doc seeds the #115#122 work.

Consider clarifying Top 5 selection criteria.

The list mixes P0 and P1 issues. While the selections appear sound (especially highlighting the brand-green token issue as a root cause), explicitly stating the ranking methodology would strengthen the executive summary—e.g., "ranked by severity, blast radius, and remediation impact" or "prioritized by contract violations first, then WCAG failures."

match the table which lists 10 hex values (rows 1–7 plus three values in row 8:
`#1a5c2a`, `#155A35`, `#4a7d5c`); either update the header text to the correct count
("Ten competing 'brand greens'") or collapse closely related entries into a
single "family" row (e.g., group `#1a5c2a` and `#155A35` as a single "dark forest"
family) and add a parenthetical note explaining grouped variants—update the
string containing "Eight competing \"brand greens\"" and the table rows
describing `#1a5c2a/`#155A35/#4a7d5c accordingly.
- Line 27: The summary "Issue counts" line is incorrect; reconcile the top-level
counts with the detailed findings by updating the bold line "**Issue counts:** 3
× P0, 11 × P1, 12 × P2, 6 × P3." to reflect the actual totals derived from the
detailed findings (P0: 4, P1: 15, P2: 19, P3: 9) and ensure the
detailed-findings section (the PX bullets under the detailed findings) and any
other summary or table reference the same numbers; modify the single-line
summary in the document to match those computed totals and, if helpful, add a
brief note that the totals are aggregated from the detailed PX bullets to
prevent future mismatches.

Multi-agent functional-correctness audit of the backend and the FE/BE

Added a second audit doc to this branch: docs/backend-contract-bug-audit.md (commit 63dd2c4).

Scope is complementary to the frontend UI audit (epic #113) — this one covers backend functional correctness + the FE↔BE API contract rather than UI quality. Multi-agent review, every finding adversarially re-verified against source: 40 candidates → 31 distinct confirmed bugs (2 critical, 6 high, 9 medium, 14 low).

Headline items worth triaging into their own issues:

  • [critical]calendar.export_to_google cross-user IDOR leaking decrypted private assignment notes (backend/routes/calendar.py:378-407)
  • [critical] realtime room chat renders raw ciphertext (Social.tsx + room_messages.text encryption boundary)
  • [high]search_course_materials leaks other users' documents into the tutor/note-chat LLM
  • [high] syllabus-extracted assignment notes persisted unencrypted

Several findings overlap the UI surface this PR's frontend audit covers (e.g. #102#112), but most are backend/contract and likely warrant a separate epic.

Maps the observability epic (Supabase events + llm_usage, fire-and-forget
write path, Logfire activation, admin analytics API, dashboard) to issues
#115-#122 with ownership, dependencies, and build order.

Added a second audit doc to this branch: docs/backend-contract-bug-audit.md (commit 63dd2c4).

Scope is complementary to the frontend UI audit (epic #113) — this one covers backend functional correctness + the FE↔BE API contract rather than UI quality. Multi-agent review, every finding adversarially re-verified against source: 40 candidates → 31 distinct confirmed bugs (2 critical, 6 high, 9 medium, 14 low).

Headline items worth triaging into their own issues:

  • [critical]calendar.export_to_google cross-user IDOR leaking decrypted private assignment notes (backend/routes/calendar.py:378-407)
  • [critical] realtime room chat renders raw ciphertext (Social.tsx + room_messages.text encryption boundary)
  • [high]search_course_materials leaks other users' documents into the tutor/note-chat LLM
  • [high] syllabus-extracted assignment notes persisted unencrypted

Several findings overlap the UI surface this PR's frontend audit covers (e.g. #102#112), but most are backend/contract and likely warrant a separate epic.

Maps the observability epic (Supabase events + llm_usage, fire-and-forget
write path, Logfire activation, admin analytics API, dashboard) to issues
#115-#122 with ownership, dependencies, and build order.

Overall codebase audit

A documentation-only branch collecting the cross-cutting audits and planning docs for Sapling. No code changes — every finding is cited to file:line and verified against the actual code. Three documents:

1. Frontend UI audit — docs/frontend-ui-audit.md

Five-dimension technical audit of frontend/ (accessibility, performance, theming, responsive, anti-patterns), scored against WCAG 2.1 AA and the design contract in .impeccable.md.

Health score: 10/20 (Acceptable — significant work needed).

DimensionA11yPerformanceThemingResponsiveAnti-Patterns
Score2/43/42/42/41/4

Core finding: the signed-in app shell is largely on-brand, but the pre-auth landing + onboarding break four of the project's own hard bans (glassmorphism, gradient text, hero-metric cards, an orphaned dark-mode stylesheet). Much of the remediation is deletion, not redesign.

Tracked by epic #113 with 11 grouped issues:

2. Backend & contract bug audit — docs/backend-contract-bug-audit.md

Functional-correctness audit of backend/ and the frontend↔backend API contract. Eight domain auditors fanned out in parallel; every candidate was handed to a separate verifier instructed to refute it. 40 candidates → 34 confirmed → 31 distinct bugs.

SeverityCountTheme
Critical2Cross-user IDOR + encrypted chat rendered as ciphertext
High6Encryption-boundary breaks, cross-user LLM context leak, agent-migration regressions, dead admin endpoint
Medium9Concurrency/idempotency, pipeline double-fire, empty-OCR persistence, missing usage limits
Low14Response-boundary ciphertext, off-by-ones, dedup/escaping, contract drift

Most urgent:calendar.export_to_google (backend/routes/calendar.py:378-407) is a cross-user IDOR that exfiltrates other users' decrypted private assignment notes — patch first, then the two encryption boundaries, then the knowledge-graph correctness cluster.

Tracked by epic #136, findings grouped into issues #123#135 (overlapping pre-existing issues #85, #72, #74, #61 were cross-linked and de-duplicated rather than re-filed).

3. Site logging & usage tracking epic — docs/observability-logging-tracking.md

Forward-looking plan (not an audit) for owned logging + usage analytics: Supabase events + llm_usage tables, a fire-and-forget write path, Logfire activation for ops/LLM tracing, an admin analytics API, and a dashboard. Broken into issues #115#122 with ownership (Luke / Andres / Jack / Jose), a dependency graph, and build order.

Scope

Documentation only — a shared docs branch consolidating audit + planning artifacts. Reviewers can treat each doc independently; the bug audits drive remediation issues, and the observability doc seeds the #115#122 work.

Overall codebase audit

A documentation-only branch collecting the cross-cutting audits and planning docs for Sapling. No code changes — every finding is cited to file:line and verified against the actual code. Three documents:

1. Frontend UI audit — docs/frontend-ui-audit.md

Five-dimension technical audit of frontend/ (accessibility, performance, theming, responsive, anti-patterns), scored against WCAG 2.1 AA and the design contract in .impeccable.md.

Health score: 10/20 (Acceptable — significant work needed).

DimensionA11yPerformanceThemingResponsiveAnti-Patterns
Score2/43/42/42/41/4

Core finding: the signed-in app shell is largely on-brand, but the pre-auth landing + onboarding break four of the project's own hard bans (glassmorphism, gradient text, hero-metric cards, an orphaned dark-mode stylesheet). Much of the remediation is deletion, not redesign.

Tracked by epic #113 with 11 grouped issues:

2. Backend & contract bug audit — docs/backend-contract-bug-audit.md

Functional-correctness audit of backend/ and the frontend↔backend API contract. Eight domain auditors fanned out in parallel; every candidate was handed to a separate verifier instructed to refute it. 40 candidates → 34 confirmed → 31 distinct bugs.

SeverityCountTheme
Critical2Cross-user IDOR + encrypted chat rendered as ciphertext
High6Encryption-boundary breaks, cross-user LLM context leak, agent-migration regressions, dead admin endpoint
Medium9Concurrency/idempotency, pipeline double-fire, empty-OCR persistence, missing usage limits
Low14Response-boundary ciphertext, off-by-ones, dedup/escaping, contract drift

Most urgent:calendar.export_to_google (backend/routes/calendar.py:378-407) is a cross-user IDOR that exfiltrates other users' decrypted private assignment notes — patch first, then the two encryption boundaries, then the knowledge-graph correctness cluster.

Tracked by epic #136, findings grouped into issues #123#135 (overlapping pre-existing issues #85, #72, #74, #61 were cross-linked and de-duplicated rather than re-filed).

3. Site logging & usage tracking epic — docs/observability-logging-tracking.md

Forward-looking plan (not an audit) for owned logging + usage analytics: Supabase events + llm_usage tables, a fire-and-forget write path, Logfire activation for ops/LLM tracing, an admin analytics API, and a dashboard. Broken into issues #115#122 with ownership (Luke / Andres / Jack / Jose), a dependency graph, and build order.

Scope

Documentation only — a shared docs branch consolidating audit + planning artifacts. Reviewers can treat each doc independently; the bug audits drive remediation issues, and the observability doc seeds the #115#122 work.

28-34: 💤 Low value

Consider clarifying Top 5 selection criteria.

The list mixes P0 and P1 issues. While the selections appear sound (especially highlighting the brand-green token issue as a root cause), explicitly stating the ranking methodology would strengthen the executive summary—e.g., "ranked by severity, blast radius, and remediation impact" or "prioritized by contract violations first, then WCAG failures."

match the table which lists 10 hex values (rows 1–7 plus three values in row 8:
`#1a5c2a`, `#155A35`, `#4a7d5c`); either update the header text to the correct count
("Ten competing 'brand greens'") or collapse closely related entries into a
single "family" row (e.g., group `#1a5c2a` and `#155A35` as a single "dark forest"
family) and add a parenthetical note explaining grouped variants—update the
string containing "Eight competing \"brand greens\"" and the table rows
describing `#1a5c2a/`#155A35/#4a7d5c accordingly.
- Line 27: The summary "Issue counts" line is incorrect; reconcile the top-level
counts with the detailed findings by updating the bold line "**Issue counts:** 3
× P0, 11 × P1, 12 × P2, 6 × P3." to reflect the actual totals derived from the
detailed findings (P0: 4, P1: 15, P2: 19, P3: 9) and ensure the
detailed-findings section (the PX bullets under the detailed findings) and any
other summary or table reference the same numbers; modify the single-line
summary in the document to match those computed totals and, if helpful, add a
brief note that the totals are aggregated from the detailed PX bullets to
prevent future mismatches.

Multi-agent functional-correctness audit of the backend and the FE/BE

Added a second audit doc to this branch: docs/backend-contract-bug-audit.md (commit 63dd2c4).

Scope is complementary to the frontend UI audit (epic #113) — this one covers backend functional correctness + the FE↔BE API contract rather than UI quality. Multi-agent review, every finding adversarially re-verified against source: 40 candidates → 31 distinct confirmed bugs (2 critical, 6 high, 9 medium, 14 low).

Headline items worth triaging into their own issues:

  • [critical]calendar.export_to_google cross-user IDOR leaking decrypted private assignment notes (backend/routes/calendar.py:378-407)
  • [critical] realtime room chat renders raw ciphertext (Social.tsx + room_messages.text encryption boundary)
  • [high]search_course_materials leaks other users' documents into the tutor/note-chat LLM
  • [high] syllabus-extracted assignment notes persisted unencrypted

Several findings overlap the UI surface this PR's frontend audit covers (e.g. #102#112), but most are backend/contract and likely warrant a separate epic.

Maps the observability epic (Supabase events + llm_usage, fire-and-forget
write path, Logfire activation, admin analytics API, dashboard) to issues
#115-#122 with ownership, dependencies, and build order.

Consider clarifying Top 5 selection criteria.

The list mixes P0 and P1 issues. While the selections appear sound (especially highlighting the brand-green token issue as a root cause), explicitly stating the ranking methodology would strengthen the executive summary—e.g., "ranked by severity, blast radius, and remediation impact" or "prioritized by contract violations first, then WCAG failures."

Added a second audit doc to this branch: docs/backend-contract-bug-audit.md (commit 63dd2c4).

Scope is complementary to the frontend UI audit (epic #113) — this one covers backend functional correctness + the FE↔BE API contract rather than UI quality. Multi-agent review, every finding adversarially re-verified against source: 40 candidates → 31 distinct confirmed bugs (2 critical, 6 high, 9 medium, 14 low).

Headline items worth triaging into their own issues:

  • [critical]calendar.export_to_google cross-user IDOR leaking decrypted private assignment notes (backend/routes/calendar.py:378-407)
  • [critical] realtime room chat renders raw ciphertext (Social.tsx + room_messages.text encryption boundary)
  • [high]search_course_materials leaks other users' documents into the tutor/note-chat LLM
  • [high] syllabus-extracted assignment notes persisted unencrypted

Several findings overlap the UI surface this PR's frontend audit covers (e.g. #102#112), but most are backend/contract and likely warrant a separate epic.

Maps the observability epic (Supabase events + llm_usage, fire-and-forget
write path, Logfire activation, admin analytics API, dashboard) to issues
#115-#122 with ownership, dependencies, and build order.

Overall codebase audit

A documentation-only branch collecting the cross-cutting audits and planning docs for Sapling. No code changes — every finding is cited to file:line and verified against the actual code. Three documents:

1. Frontend UI audit — docs/frontend-ui-audit.md

Five-dimension technical audit of frontend/ (accessibility, performance, theming, responsive, anti-patterns), scored against WCAG 2.1 AA and the design contract in .impeccable.md.

Health score: 10/20 (Acceptable — significant work needed).

DimensionA11yPerformanceThemingResponsiveAnti-Patterns
Score2/43/42/42/41/4

Core finding: the signed-in app shell is largely on-brand, but the pre-auth landing + onboarding break four of the project's own hard bans (glassmorphism, gradient text, hero-metric cards, an orphaned dark-mode stylesheet). Much of the remediation is deletion, not redesign.

Tracked by epic #113 with 11 grouped issues:

2. Backend & contract bug audit — docs/backend-contract-bug-audit.md

Functional-correctness audit of backend/ and the frontend↔backend API contract. Eight domain auditors fanned out in parallel; every candidate was handed to a separate verifier instructed to refute it. 40 candidates → 34 confirmed → 31 distinct bugs.

SeverityCountTheme
Critical2Cross-user IDOR + encrypted chat rendered as ciphertext
High6Encryption-boundary breaks, cross-user LLM context leak, agent-migration regressions, dead admin endpoint
Medium9Concurrency/idempotency, pipeline double-fire, empty-OCR persistence, missing usage limits
Low14Response-boundary ciphertext, off-by-ones, dedup/escaping, contract drift

Most urgent:calendar.export_to_google (backend/routes/calendar.py:378-407) is a cross-user IDOR that exfiltrates other users' decrypted private assignment notes — patch first, then the two encryption boundaries, then the knowledge-graph correctness cluster.

Tracked by epic #136, findings grouped into issues #123#135 (overlapping pre-existing issues #85, #72, #74, #61 were cross-linked and de-duplicated rather than re-filed).

3. Site logging & usage tracking epic — docs/observability-logging-tracking.md

Forward-looking plan (not an audit) for owned logging + usage analytics: Supabase events + llm_usage tables, a fire-and-forget write path, Logfire activation for ops/LLM tracing, an admin analytics API, and a dashboard. Broken into issues #115#122 with ownership (Luke / Andres / Jack / Jose), a dependency graph, and build order.

Scope

Documentation only — a shared docs branch consolidating audit + planning artifacts. Reviewers can treat each doc independently; the bug audits drive remediation issues, and the observability doc seeds the #115#122 work.

Overall codebase audit

A documentation-only branch collecting the cross-cutting audits and planning docs for Sapling. No code changes — every finding is cited to file:line and verified against the actual code. Three documents:

1. Frontend UI audit — docs/frontend-ui-audit.md

Five-dimension technical audit of frontend/ (accessibility, performance, theming, responsive, anti-patterns), scored against WCAG 2.1 AA and the design contract in .impeccable.md.

Health score: 10/20 (Acceptable — significant work needed).

DimensionA11yPerformanceThemingResponsiveAnti-Patterns
Score2/43/42/42/41/4

Core finding: the signed-in app shell is largely on-brand, but the pre-auth landing + onboarding break four of the project's own hard bans (glassmorphism, gradient text, hero-metric cards, an orphaned dark-mode stylesheet). Much of the remediation is deletion, not redesign.

Tracked by epic #113 with 11 grouped issues:

2. Backend & contract bug audit — docs/backend-contract-bug-audit.md

Functional-correctness audit of backend/ and the frontend↔backend API contract. Eight domain auditors fanned out in parallel; every candidate was handed to a separate verifier instructed to refute it. 40 candidates → 34 confirmed → 31 distinct bugs.

SeverityCountTheme
Critical2Cross-user IDOR + encrypted chat rendered as ciphertext
High6Encryption-boundary breaks, cross-user LLM context leak, agent-migration regressions, dead admin endpoint
Medium9Concurrency/idempotency, pipeline double-fire, empty-OCR persistence, missing usage limits
Low14Response-boundary ciphertext, off-by-ones, dedup/escaping, contract drift

Most urgent:calendar.export_to_google (backend/routes/calendar.py:378-407) is a cross-user IDOR that exfiltrates other users' decrypted private assignment notes — patch first, then the two encryption boundaries, then the knowledge-graph correctness cluster.

Tracked by epic #136, findings grouped into issues #123#135 (overlapping pre-existing issues #85, #72, #74, #61 were cross-linked and de-duplicated rather than re-filed).

3. Site logging & usage tracking epic — docs/observability-logging-tracking.md

Forward-looking plan (not an audit) for owned logging + usage analytics: Supabase events + llm_usage tables, a fire-and-forget write path, Logfire activation for ops/LLM tracing, an admin analytics API, and a dashboard. Broken into issues #115#122 with ownership (Luke / Andres / Jack / Jose), a dependency graph, and build order.

Scope

Documentation only — a shared docs branch consolidating audit + planning artifacts. Reviewers can treat each doc independently; the bug audits drive remediation issues, and the observability doc seeds the #115#122 work.

28-34: 💤 Low value

Consider clarifying Top 5 selection criteria.

The list mixes P0 and P1 issues. While the selections appear sound (especially highlighting the brand-green token issue as a root cause), explicitly stating the ranking methodology would strengthen the executive summary—e.g., "ranked by severity, blast radius, and remediation impact" or "prioritized by contract violations first, then WCAG failures."

- Around line 71-92: The summary claim "Eight competing 'brand greens'" doesn't
match the table which lists 10 hex values (rows 1–7 plus three values in row 8:
`#1a5c2a`, `#155A35`, `#4a7d5c`); either update the header text to the correct count
("Ten competing 'brand greens'") or collapse closely related entries into a
single "family" row (e.g., group `#1a5c2a` and `#155A35` as a single "dark forest"
family) and add a parenthetical note explaining grouped variants—update the
string containing "Eight competing \"brand greens\"" and the table rows
describing `#1a5c2a/`#155A35/#4a7d5c accordingly.
- Line 27: The summary "Issue counts" line is incorrect; reconcile the top-level
counts with the detailed findings by updating the bold line "**Issue counts:** 3
× P0, 11 × P1, 12 × P2, 6 × P3." to reflect the actual totals derived from the
detailed findings (P0: 4, P1: 15, P2: 19, P3: 9) and ensure the
detailed-findings section (the PX bullets under the detailed findings) and any
other summary or table reference the same numbers; modify the single-line
summary in the document to match those computed totals and, if helpful, add a
brief note that the totals are aggregated from the detailed PX bullets to
prevent future mismatches.

Added a second audit doc to this branch: docs/backend-contract-bug-audit.md (commit 63dd2c4).

Scope is complementary to the frontend UI audit (epic #113) — this one covers backend functional correctness + the FE↔BE API contract rather than UI quality. Multi-agent review, every finding adversarially re-verified against source: 40 candidates → 31 distinct confirmed bugs (2 critical, 6 high, 9 medium, 14 low).

Headline items worth triaging into their own issues:

  • [critical]calendar.export_to_google cross-user IDOR leaking decrypted private assignment notes (backend/routes/calendar.py:378-407)
  • [critical] realtime room chat renders raw ciphertext (Social.tsx + room_messages.text encryption boundary)
  • [high]search_course_materials leaks other users' documents into the tutor/note-chat LLM
  • [high] syllabus-extracted assignment notes persisted unencrypted

Several findings overlap the UI surface this PR's frontend audit covers (e.g. #102#112), but most are backend/contract and likely warrant a separate epic.

Maps the observability epic (Supabase events + llm_usage, fire-and-forget
write path, Logfire activation, admin analytics API, dashboard) to issues
#115-#122 with ownership, dependencies, and build order.

28-34: 💤 Low value

Consider clarifying Top 5 selection criteria.

The list mixes P0 and P1 issues. While the selections appear sound (especially highlighting the brand-green token issue as a root cause), explicitly stating the ranking methodology would strengthen the executive summary—e.g., "ranked by severity, blast radius, and remediation impact" or "prioritized by contract violations first, then WCAG failures."

In `@docs/frontend-ui-audit.md`:
- Around line 71-92: The summary claim "Eight competing 'brand greens'" doesn't
match the table which lists 10 hex values (rows 1–7 plus three values in row 8:
`#1a5c2a`, `#155A35`, `#4a7d5c`); either update the header text to the correct count
("Ten competing 'brand greens'") or collapse closely related entries into a
single "family" row (e.g., group `#1a5c2a` and `#155A35` as a single "dark forest"
family) and add a parenthetical note explaining grouped variants—update the
string containing "Eight competing \"brand greens\"" and the table rows
describing `#1a5c2a/`#155A35/#4a7d5c accordingly.
- Line 27: The summary "Issue counts" line is incorrect; reconcile the top-level
counts with the detailed findings by updating the bold line "**Issue counts:** 3
× P0, 11 × P1, 12 × P2, 6 × P3." to reflect the actual totals derived from the
detailed findings (P0: 4, P1: 15, P2: 19, P3: 9) and ensure the
detailed-findings section (the PX bullets under the detailed findings) and any
other summary or table reference the same numbers; modify the single-line
summary in the document to match those computed totals and, if helpful, add a
brief note that the totals are aggregated from the detailed PX bullets to
prevent future mismatches.

Multi-agent functional-correctness audit of the backend and the FE/BE
API contract. 40 candidates verified adversarially -> 34 confirmed
(31 distinct after merges): 2 critical, 6 high, 9 medium, 14 low.
Each finding cited to file:line with a suggested fix.

Added a second audit doc to this branch: docs/backend-contract-bug-audit.md (commit 63dd2c4).

Scope is complementary to the frontend UI audit (epic #113) — this one covers backend functional correctness + the FE↔BE API contract rather than UI quality. Multi-agent review, every finding adversarially re-verified against source: 40 candidates → 31 distinct confirmed bugs (2 critical, 6 high, 9 medium, 14 low).

Headline items worth triaging into their own issues:

  • [critical]calendar.export_to_google cross-user IDOR leaking decrypted private assignment notes (backend/routes/calendar.py:378-407)
  • [critical] realtime room chat renders raw ciphertext (Social.tsx + room_messages.text encryption boundary)
  • [high]search_course_materials leaks other users' documents into the tutor/note-chat LLM
  • [high] syllabus-extracted assignment notes persisted unencrypted

Several findings overlap the UI surface this PR's frontend audit covers (e.g. #102#112), but most are backend/contract and likely warrant a separate epic.

Maps the observability epic (Supabase events + llm_usage, fire-and-forget
write path, Logfire activation, admin analytics API, dashboard) to issues
#115-#122 with ownership, dependencies, and build order.

Roadmap was created in a prior session but never committed (untracked,
not gitignored). Add it to the repo and extend it with the unified
issue-tag conventions (P0-P3 / EPIC), label glossary, and per-domain
ownership mapping.

In `@docs/observability-logging-tracking.md`:
- Around line 73-83: The fenced dependency-graph block starting with the line
"`#115` (tables)" is missing a language identifier which triggers markdownlint
MD040; update the code fence opening to include a language (e.g., change "```"
to "```text") so the block is treated as plain text (or use "```mermaid" if
converting to a mermaid graph), ensuring the block containing "`#115` (tables)"
through "`#119` (Logfire activation) — independent, ship anytime" passes linting.
In `@ROADMAP.md`:
- Around line 30-32: Add a language identifier to the fenced code block
containing "[P0] <imperative summary> [P1] … [P2] … [P3] … [EPIC] <name>" by changing the opening fence from ``` to ```text so the block is
explicitly marked (this fixes MD040 lint failures).

- frontend-ui-audit: fix issue-count summary (3/11/12/6 -> 4/15/19/9) to
match the detailed findings; correct 'eight' -> 'ten' competing greens
(table lists 10 distinct values)
- ROADMAP + observability: add language tag to fenced blocks (markdownlint MD040)
