fix(citadel): apply Tier 1 relevance fixes, JD coverage 51% -> 68%

Browse Source 
All three Tier 1 items from the critique, all honestly available, no
claim altered.

The R2 vocabulary now appears where R2 is actually evidenced: the SW-7
bullet carries ingestion and lifecycle, and SW-1 carries transformation
and storage. R2 was the single core responsibility scored Direct, and
the document had been proving it in substance while missing it in the
JD's own words. SW-2 now names the Oracle/Kafka/Python/Teradata estate a
distributed system he operates - not one he designed, which stays a gap.
The second skills line is relabelled "Distributed systems" and names
distributed databases explicitly, closing the fifth preferred-technology
hit that Phase 0 counted as Direct but the resume never actually wrote.

Recorded what was deliberately not added, because raising keyword
coverage is exactly where a later run would be tempted to overreach:
"scalable" is an unverified scale claim, and SDK, high-throughput,
data-intensive, simulation, model development and self-service have no
canonical evidence. Verified still absent after the edit.

Scope kept to what was approved. The user said "tier 1 fixes", so the
Tier 2 headline retitle - "Production Data Platforms on AWS", the line
most likely to draw the opening challenge from a technical reviewer -
was left in place for them to decide.

Validator PASS with zero warnings: the 58% cadence warning cleared as a
side effect, because restructuring two bullets with em-dashes broke the
comma-list pattern the checker keys on. Still exactly 2 pages, zero
overfull/underfull boxes, PDF re-inspected.

Critique marked STALE - it scored the pre-edit document.

## Edit History
### Edit 1 (2026-08-26): Tier 1 relevance fixes
- **Source:** `critique_citadel_securities_platform_engineer.md` Tier 1 items 1-3. User approved
"tier 1 fixes" only; the Tier 2 headline retitle was deliberately NOT applied.
- **Changes (all MODIFY, no budget change):**
1. SW-7 bullet -> now carries **ingestion** and **lifecycle**: "from source-system ingestion
through to the metadata and lineage in Atlassian Compass that keep each product discoverable
across its lifecycle."
2. SW-1 bullet -> now carries **transformation** and **storage**: "transformation and storage on
Glue, Athena with Apache Iceberg and Redshift, orchestration in Airflow". Scope hedge
("contributing to the wider company migration programme") retained.
3. SW-2 bullet -> names the estate a **distributed system** he operates, not designed.
4. Skills line 2 relabelled **"Distributed systems"** and now names **distributed databases
(Teradata, Redshift, Athena/Iceberg)** - closes the fifth preferred-technology hit that Phase 0
claimed as Direct but the document never wrote.
- **Not added, deliberately:** scalable (unverified scale claim), SDK / high-throughput /
data-intensive / simulation / model development / self-service (zero canonical evidence).
Verified still absent after the edit.
- **Verification:** validator **PASS, 0 warnings** (the cadence warning cleared as a side effect -
restructuring SW-1/SW-2 with em-dashes broke the comma-list pattern). Compiles to exactly
**2 pages**, zero overfull/underfull boxes, PDF re-inspected clean.
| Metric | Before | After | Delta |
|---|---|---|---|
| Pages | 2 | 2 | 0 |
| Validator errors | 0 | 0 | 0 |
| Validator warnings | 1 (cadence 58%) | **0** | -1 |
| Bullets | 13 | 13 | 0 |
| JD term coverage | 19/37 (51%) | **25/37 (68%)** | +6 |
**Estimated Document Quality ~91/100** (relevance 10 -> ~14, mechanics 9 -> 10). Estimate only -
not a re-scored critique.
## Status
- Phase 0: **DONE** (2026-08-25)
- Phase 1: **DONE** (2026-08-26) — 13 bullets confirmed
- Phase 2: **DONE** (2026-08-26) — resume compiled and verified
- Cover Letter: **PENDING** (decision YES — PP-1 domain story needs prose)
- Critique: **CURRENT** (2026-08-26) — **Document Quality 86/100**, Evidence Fit 71, Channel Weak.
- Critique: **STALE** (scored 86/100 on 2026-08-26, before Edit 1) — **Document Quality 86/100**, Evidence Fit 71, Channel Weak.
No Tier 1 truth findings; validator PASS. Three Tier 1 relevance fixes (~+4), all honestly
available: (1) R2's own vocabulary — ingestion/transformation/storage/lifecycle — is absent
despite R2 being the single Direct core responsibility; (2) "distributed systems" never appears
